2024-02-02wifi: iwlwifi: mvm: d3: implement suspend with MLOJohannes Berg1-25/+54
When using MLO, we need to have only a single link active when entering suspend and of course most of the code also needs to be adjusted to not use deflink, apart from older code that's not used with MLO-capable firmware. Implement that. Note that the link selection currently prefers the "best" link, which might really not be the best for D3, but that can be fixed later once we agree.

With MLO connections we need to let the firmware pick the rate as we don't know the link the frame might be transmitted on (in some cases we do know, but we'd rather always use the FW and find bugs.) We _did_ end up finding bugs and fixing them, but older devices likely won't get fixed as we don't have a need for this there, they cannot support MLO.

2024-01-26wifi: iwlwifi: add support for a wiphy_work rx handlerMiri Korenblit3-11/+54
The wiphy_work infra ensures that the entire worker will run with the wiphy mutex. It is useful to have RX handlers running as a wiphy_work, when we don't want the handler to run in parallel with mac80211 work (to avoid races). For example - BT notification can disable eSR starting from the next patch. In ieee80211_set_active_links we first check that eSR is allowed, (drv_can_activate_links) and then activate it. If the BT notif was received after drv_can_activate_links (which returned true), and before the activation - eSR will be activated when it shouldn't. If BT notif is handled with the wiphy mutex, it can't run in parallel to ieee80211_set_active_links, which also holds that mutex. Add the necessary infrastructure here, for use in the next commit.

If the STEP (the interface between MAC and PHY) is in URM (a lower speed mode) then we cannot use 320 MHz MCS > 9. Therefore, limit the MCS in our capabilities in this case.
